Abstract

L'invention concerne un véhicule, en particulier un motocycle, comportant un moteur et un vilebrequin qui est accouplé à une boîte de vitesses par l'intermédiaire d'un embrayage, un dispositif de limitation du couple étant disposé dans le trajet du couple de rotation entre l'embrayage et une sortie de la boîte de vitesses. Le dispositif de limitation du couple est conçu de telle sorte que le couple de poussée maximum pouvant être transmis, en mode poussé, par la boîte de vitesses au moteur est inférieur au couple d'entraînement maximum pouvant être transmis du moteur à la boîte de vitesses lors du fonctionnement normal.
